Beitknown that l, FREDERIGIE. Baena, a citizen ofthe United .StatesnofAmerica, andk resident of, Winthrop Harbor, Lake county, Illinois, haveinvented a .certain new and useful Improvement in Drainage-Excavators,of which the followingis a speci* fication. I. I. 1i

, My invention relates `to excavators for making ditches, and moreparticularly those for use in, making irrigation ditches and forfmakingditches I,with a dike at one or eaohside of the ditch., I

The principal `object of my invention is ltosprovide a machine havingmeansfor cuti ting adltch,` and provided with devices for smoothing ortrimming the spoil bank the machinemoves along', whereby the excavateddirt is' converted into a dike during theoper ation Aof the means .forcutting the ditch, the said devices being of such `character that theinner face of the dike is given a slope of the proper character,I itIbeing desirable that the same caused to assumethe .angle of reposeA cf`the` excavated dirt, whereby .the loosefmaterialsare converted into Iadike of satisfactory form as theII machine travels along in thedirection necessary for the @It is I,alsoan object to provide certaindetails, and', featuresf yof construction and combinations ,tendingytIoIIincrease.` the general efficiency land-I serviceability of I aIcombined ditchingmachinaand dilie builder of this particularlcharacter.,I I 1 I I I To these and other useful ends my inven`` tionconsifsts inmatters hereinafter set 'forth anllamedlj I I.

Specification of Letters raient.

As thus illustrated, my invention comro ritnhnnrcn c.

prises a body A mounted upon front wheels B and rear caterpillars@ thelatter `being operated or driven bythe engine D any suitable or desiredmanner. understood thatthe said enginemand cateri pillars may be of anysuitable known or approved character, and `that any suitable means maybe employed for controlling the forward travel of the machine. i

rfhe excavating apparatus comprises a ro`- tary wheel E mounted ontherear end of a beam F, which latter is supported to swing up and downon the shaft G at `therear of lt willbe the body of the machine.Preferably, the

said shaft issupported in bearings onthe frame work ci of said body, andis disposed horizontally and transversely of the direction of the ditch,being located a suitable distance above the body of the machine, or

above the surface of the ground. Thezbeam F 1s connected with theframing a by means of an adjustable` connection H, of any suitablecharacter, whereby the 'wheel E may be raised and lowered by changingthe angle of the beam l, in a manner that will be readily understood.The adjusting connection H can be operated by hand, or itcan be operatedby power and through the means of suitableconnection'with the engine.The i shaft G is provided with sprocket wheels g upon which aresupported the spriocketbelts g1, said beltsextending around the wheel E,the latter being operated withsprocket teeth of any suitable characterfor this" purpose.` I

The excavating buckets 12," of any suitable forni or character, aremounted" on said" sprocket belts, and "arethereby `adapted travel in thedirection indicated by the arrowin Fig-gl, whereby eachbucket `taires aload at the bottom of the ditch andIthen travels upward to the point ofdischarge above. u said point of` discharge is approximately above and alittle to the right of the shaft Gr,

as shown in Fig; l, andany suitablemeans can be employed for causing thebuckets to successively discharge their loads as they turn upside downat this point and pass around the said shaft. The wheel E is providedwith side cutters c for forming` the sides of the ditch, these cuttersbeing preferably bars which aresuitably" fastened -to With theconstruction shown," the the wheel, and which aren radially di`spo`sed`relative tothe axis of said wheel. It will also be seen, however, thatthese cutters, as shown in Fig. 3, are farther apart at their upperends, when in the ditch, than at their lower ends; and that for thisreason the sides of the ditch incline outwardly to some extent and areof a sloping character. The dirt shaved olf by these cutters is taken upby said bucketsvand dumped at the points above mentioned. The device forconverting the excavated dirt into a dike at one side of the ditch, orat both sides thereof, comprises the cutters e1 which are suitablyfastened to the sides of the wheel E, and which are so arranged that ineffect they form outwardly tapered hubs for the wheel, which hubs aresecured in any suitable manner to the shaft or journal e2 that rotatesin suitable bearings e3, or which is supported in any other suitablemanner on the lower end of the tilting beam. As shown in Fig. 3, it willbe seen that the cutters c1 are disposed at an angle to the cutters e,so that any cutter e and the adjacent cutter el form an obtuse anglebetween them, the apex of said angle being. slightly rounded at e4 inthe manner shown, it being observed that these rounded portions of thecutters are immediately above the surface of the ground. Coperating withthese cutters e1 in forming the dikes X at each side of the ditch arethe rearwardly extending conveyers I which are suitably supportedon therear end of the body A and which are arranged with their forward ends inposition to receive the dirt from the spouts J, said spouts being at thelower end of a hopper K which receives the dirt directly from thebuckets. These conveyers I are of any suitable character, and areoperated through the means of any suitable power transmitting connectionwith the enn gine D on the machine body. It will also be seen that therear ends of these conveyers I are directly in front `of and in linewith the cutters e1, whereby the latter are compelled to plow throughthe spoil or ridges of loose dirt discharged upon the vground by saidconveyers.y As the excavator travels slightly forward, these cutters e1trim or shave the inner sides of the spoil banks in such manner as toconvert the latter into dike's of the proper character, the inner face or, inclined surface of each dike having the angle of repose of the loosematerials or exl vcutters el to prevent the formation of a vers bermbetween the dike and the side of the ditch, inasmuch as the loose dirtdoes not leave any exposed ground surface between the dike andthe upperedge of the side of the ditch. Thus the two dikes are formed with gentlysloping inner sides or faces, and these inner sides are curved wherethey join the sides of the ditch, thus preventing an abrupt angle atthis point, and insurin the formation of a ditch having dikes whic 1will remain firmly and solidly in place without danger of the loose dirtsliding into the ditch after the machine has traveled forwardthat is tosay, the possibility of the loose dirt sliding into the ditch is greatlyreduced by smoothing or iiattening of the inner sides of the (likes, andby the manner in which the loose dirt is left along the edges of theditch.

The devices el, it will be seen, only operate above ground on the loosedirt of the spoil banks, and do not cut the trench in the ground. Butboth the trench-cutting means and said devices operate about the samehorizontal axis (shaft e2), which latter is transverse of the ditch.

What I claim as my invention is:

l. An excavator comprising means for cutting a ditch, apparatus fordischarging the excavated dirt at the side of the ditch, to form a spoilbank, mechanism for slowly moving the machine forward during theoperation of said means, and devices for properly sloping the face ofsaid bank to form a dike as the machine moves along, said meansincluding a wheel having cutters for forming a ditch with sloping sides,and said devices including cutters disposed in such position that theface of the dike forms an obtuse angle with the adjacent side of theditch.

2. An excavator comprising means for cutting a ditch, apparatus fordischarging the excavated dirt at the side of the ditch, to form a spoilbank, mechanism for slowly moving the machine forward during theoperation of saidmeans, and devices for properly sloping the face ofsaid bank to form a dike as the machine moves along, said meansincluding a wheel, link belts traveling on said wheel, instrumentalitiesfor operating said'belts to rotate said wheel, buckets on said linkbelts, and said devices consisting of cutters forming the hub of saidwheel.
